A study says today's are growing up more than before. Researchers looked at on the behaviour of 8 million teens in seven countries over the past 40 years. They said that compared to teenagers from the 70s, 80s and 90s, today's , "are taking longer to engage in the pleasures and the responsibilities of ". A professor said: "The developmental pathway has slowed down." She said today's 18-year-olds are like how 15-year-olds used to be. She said teenagers are taking a lot fewer than they did before.
Today's teenagers are taking to do things their parents did. They are when they date, less to work part-time, and likely to drive. The professor said they have a, "slow life ". More teenagers are living with their parents instead of renting their room. One of the reasons for this behaviour is how much time teenagers spend . The Internet is keeping teens on social , looking at videos or playing games of living in the "real world". Another reason is parents do too for their children and protect them too much.
